Turning on the lathe is one of the most common metalcutting operations. Lathes are particularly suited to machining relatively long, cylindrical workpieces, yet can create a variety of parts ranging from small watch components to massive propeller shafts.
Part of the Fundamental Manufacturing Processes Video Series, this program provides a broad understanding of the turning process including segments on basic lathe turning, lathe types, automation and tool arrangements, turning operations, cutting tool factors, and operating parameters.
The basic lathe turning segment focuses on the elements that the lathe. Terms such as spindle, headstock, carriage, cross slide compound rest, tool post, and tailstock are defined and detailed. Lathe workholding devices such as chucks, collets, mandrels, face drivers, and between centers turning are also covered.
The lathe types segment looks at the various types of lathes, including engine lathe, CNC lathes, turn-mill lathes, vertical lathes, swiss-type CNC lathes, automatic screw machines, and more.
The automation and tool arrangements segment details bar stock loaders, sensors, gantry loading systems, lathe turrets, and gang tooling.
The turning operations segment covers operations such as straight turning, taper turning, contour turning, thread chasing, facing, holemaking, reaming, tapping, and more.
The cutting tool factors segment explores the various cutting tool materials and geometries, as well as the use of cutting fluids in turning.
The operating parameters segment features the variables of cutting speed, feed rate, and depth of cut.
